I'm confused after 2 minutes of this video on acceleration; It starts with telling us that a car acclerates at 8m/s/s for 5 seconds. Then it gives a data chart which includes the car's position at each time interval. The data is as follows. O seconds; O metres 1 second; 4 metres 2 seconds; 16...

Hi, a teacher and I have been looking for websites to take Math/Physics exercises from, put them together as a test, print it and pass it to students. I know there are many websites that give you tools to write your own exercises (mainly many LMSes). But we'd like to pick exercises already...

They have been discussing installing locks on classroom doors that can be locked from the inside of the classroom in response to school shootings. Why are they discussing this instead of talking about banning guns? Wouldn't banning guns be easier?

Hi all, I'm seriously considering going back to college for a degree in engineering, specifically mechanical. I meet the aptitude tests, all of the interests, want to design and create, etc. I've definitely got the bug. I do DIY carpentry jobs on the side, I've got technical degrees in machine...

I wasn't sure if this should be in General Discussion, or in this forum. However, since it affects students and it depends on the classroom policy of the instructor, I thought it should be in here. This is something many of us instructors have to deal with, something that was never an issue...

I plan on teaching high school education because I am crazy and enjoy learning. Anyway I noticed that in my school if a teacher is strict or rude the students tend to be extremely rude and act poorly out of spite. And teachers who are very kind and still tries to ensure all work is done, the...

My classmates and I were discussing the impulse-momentum theorem and how they correlate. The example problem consisted of two cars running into solid surfaces at the same velocity. One car ran into a brick wall and came to a complete stop. The other car ran into a haystack and came to a...

I'm looking for tested and proven technology for the high school chemistry class, can anyone suggest anything? It's a passion of mine to improve labs, and teaching lessons. Lately there has been a lot of emphasis on technology in the classroom. How do you implement any technology when there are...

I'm a first-year undergraduate student in mathematics and physics. In my Chemistry Lab class we've recently completed a graphical representation of data assignment and it was interesting. My question is, what can I do in regards to mathematics and physics, or something interesting in general...

I am teaching summer school this year in math. Our summer school is only 12 days and is only available to students who have failed the class. When looking at the requirements for teachers this year, I noticed one thing was each teacher is going to be required to add in a participation grade. I...

hi this is in my physics classroom. what is this object?

I'm a senior in high school taking AP Physics II, and I was recently elected as the president of my schools Science Club. Our first thing to do is to go to the local elementary schools and give interesting physics demonstrations to the younger students grades K-6. I really enjoy space and I know...

I am not an educator. However, I just read a fascinating article that just screamed "education issue" as I read it. The article was: The point of the article is that I and almost all other students of engineering or science were taught that the Tacoma Bridge (known as Galloping Gertie)...

I had an interesting idea in a dream, and unlike most dream ideas it still made sense when I woke up. When I'm teaching a large lecture, I know there are students who are afraid to ask questions because it feels awkward being that one voice in a hundred. My idea is to provide some sort of...

An old concept previously used by Socrates and currently by Montessori schools that thinking can lead to knowledge is better than trying to provide knowledge to develop thinking is being reintroduced into our educational system. This educational model has been expedited by the internet by...

I'm about to take my first classroom math course and am kind of nervous about it. I'm good enough at math but very slow, this is why I have typically done online maths till now. I could take a week to do something I didn't comprehend. What tips can you guys give someone who is not quite as fast...

The school in which I teach is going to pilot a tablet for each student in a class next year. My physics class is going to be part of this pilot. Currently they are looking at ipad/surface/chromebook. Does anyone have input good or bad on any of these for use in class as well as with labs...

What do you think about kids getting iPads in the classroom? I think it's a fine idea if the money is there. However there is a school in my city which was just called out on because to be able to afford to give each student an Ipad they canceled all tutoring in the school. That is straight...

Homework Statement A large classroom has 100 students. 30 speak spanish, 25 speak italian, and 55 speak neither. a). how many speak both? b).A student who speak italian is chosen at random. What is the probability that he/she speaks spanish? Homework Equations P(A) = 1 -...

I am in my last year of high school. I do not know if I will become a mathematician or physicist. Right now, I enjoy physics more but I will double major in math and physics anyway. I know that research experience is important in undergraduate physics. However, how important is undergraduate...

I was thinking lately of taking a few battery-operated devices and converting them such that they could run off other energy sources (like outlets). But, I was wondering what concepts should be taken into consideration? For example, I have a fan that runs off of two D 1.5V batteries; this is...

Right now, I am in student in graduate school MAT program, so I can be come a high school physics teacher. One of the things I am really struggling with is understanding and applying informal assessments. Beyond simple student feedback, does anyone know of concrete examples of informal...

Now I'm sure many of you have wished that you were better able to pay attention in the classroom. Well, what if the teacher gained the ability to monitor the attentiveness of everyone in the classroom? how can this be done? simple, attach a few EEG electrodes to monitor the activity in a...

I need to do a presentation to teach the rest of my class about Gamma rays. We need to do some sort of experiment to demonstrate Gamma Rays. Any ideas?

This discussion varies over many topics, so I'm posting here. First off, I'm working on a NASA grant. We're doing the "Global Climate Change Education" grant. We are writing high school labs. The basic idea is for the lab to mostly be a typical lab, but have some aspect of climate...

I'm seeking some basic survey info about learning preferences. Of the following, which would you rather take? 1) a traditional classroom course 2) a completely online course 3) a traditional classroom course with some online enhancements (ex. lecture podcasts, interactive demonstrations...

We were in our intro physics class and the prof was talking about ideal gas. He asked what are the qualities of ideal gas to which I replied "quiet and not smelly". Classroom exploded

I am resuming my education after a two year break (due to a career change). I am a little confused as to how to handle my current situation regarding math. When I left school two years ago, I was ready for calculus having completed college algebra and trigonometry. Since then, my algebra...

Homework Statement Considering the Earth magnetic field, I need to find the magnetic energy stored in our classroom.Homework Equations U= (1/2*\mu) B2 The Attempt at a Solution Any suggestions?

I have a serious question to ask of anyone who can be of help. It is necessary that I say a few things about myself first so please read on I promise that this has to do with physics. Ever since I was 6 years old, I wanted to be a nature photographer. I worked for 7 years after high school as...

Homework Statement In a classroom demonstration, a beam of coherent light of wavelength 550 nm is incident perpendicularly onto a pair of slits. Each slit has a width w of 1.2 x 10^-6 m, and the distance d between the centers of the slits is 1.8x10^-5 m. The class observes light and dark...

I am in 9th grade and am starting to read on physics and learn more on my own rather than in school(I could learn everything they teach a day in school in an hour). I have just finshed a conceptual physics book that is an introductory to physics without the complex math (although I am starting...

Hello this is my first posting. I have a device that I acquired from my old high school. It is a demonstration unit of AC and DC electricity generation. It has a small crank on one end. It is not equipped with permanent magnets in either the field or the armature. If I test the voltage off the...

n people sit down at random a classroom containing n+p seats. There are m red seats (m<=n) in the classroom, what is the probability that all red seats will be occupied? I know the bottom should be n+p choose n but I'm not sure what the numerator should be, any ideas would be great. I was...

I am attempting to determine two probabilities in a scenario in which a classroom of 28 students with assigned seating is scrambled randomly and blindly reseated by the teacher. What is the probability that exactly one student is reseated in his or her original seat, and what is the probability...

Hey there guys. I know there are plenty of teachers here, so I was hoping for some input: For one of my classes, I am supposed to redesign the "typical university classroom" (though I am sure the the idea extends to the high-school level too). The objectives are as follows: So far we...

Im still in high school, and although our school doesn't offer any astrophysics courses, I was hoping on reading some books to learn more. I've read the Inflationary Universe ... any other suggestions?

Is there an amazing way I can demonstrate Rotational Kinetic Energy in a classroom? It's for a presentation and I've looked and thought about some experiments but they involve Angular Momentum which another group has to present/explain. Sorry if this is in the wrong section, it's my first...

So I have this question, and while I may not be in a position to apply it now, it is something I'm curious about. But for you guys who've already graduated and are engineers and have been for some time, how do you motivate yourself to keep learning? What sources do you utilize for these...

Helo everyone, can somebody post the best algorithm/strategy to solve indefinite integral questions which are usually asked to undergraduates. The most general set of steps that can be applied to every question one encounters in the classroom. Algo that though may be proved to be inconvenient...

Hello again guys, Its been awhile since I have been able to get back here, but I have been really busy. I am currently a freshman in the engineering school at the University of Michigan. We have just got a project and I thought that it would be nice to get the input of fellow PF members...

I've been reading a lot about this controversy about teaching evolution in classrooms, and I have to say that I'm just baffled that we're even arguing about whether or not evolution should be taught in schools. Conservative christians have over taken this country and seem to want to do away with...

hi can anyone please suggest an interesting, good practical experiment that i can carry out in a classroom explaining a physics concept. Its a project i have to do. any help would be greatly appreciated, thanx
